A Wealth of Knowledge Tailored to Your Needs / Categorization
Safari has added the ability for users to categorize the material in its digital library according to the user’s own preferences. Users can now create and fill their own categories of preferred titles.

Improved Readability of the Content You Want
With Safari 6.0, users have the ability to make inline notes in the actual text they are reading. They can now dog-ear or bookmark specific pages. They can make notes while reading on a given page, AND they can share these notes and bookmarks with others – making Safari Books Online a more powerful learning and teaching tool.
